Amorphous silicon under mechanical shear deformations: shear velocity and temperature effects

, 2011
Mechanical shear deformations lead, in some cases, to effects similar to those resulting from ion irradiation. Here we characterize the effects of shear velocity and temperature on amorphous silicon (\aSi) modelled using classical molecular dynamics ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Shearing Deformation of Fabrics

Journal of the Textile Machinery of Japan - Proceedings -, 1968
Studies on the shearing deformation of fabrics are surveyed.The factors affecting the shearing behavior are the inter-yarn friction, the elastic deformation at the crossing point of warp and weft, and yarn flexural rigidity. These factors are subjected to mechanical properties of the fibers and the mechanical structure of the fabrics. Shearing behavior

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Thermal flexural analysis of cross-ply laminated plates using trigonometric shear deformation theory

Latin American Journal of Solids and Structures
Thermal stresses and displacements for orthotropic, two-layer antisymmetric, and three-layer symmetric square cross-ply laminated plates subjected to nonlinear thermal load through the thickness of laminated plates are presented by using trigonometric ...

The motion of a deformable drop in a second-order fluid [PDF]

, 1979
The cross-stream migration of a deformable drop in a unidirectional shear flow of a second-order fluid is considered. Expressions for the particle velocity due to the separate effects of deformation and viscoelastic rheology are obtained.

Shear dominated deformation with curved beaks in folding–shearing

The International Journal of Advanced Manufacturing Technology
Abstract The deep drawing process in the automotive industry generates up to 45% material waste. To address this issue, the folding–shearing process was developed as a drop-in solution, enabling the formation of parts in pure shear with minimal thickness variation.

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials

Advanced Engineering Materials, EarlyView.
This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...

Experimental analysis and modeling of orthogonal cutting using material and friction models [PDF]

, 2007
In this study, a process model for orthogonal cutting processes is proposed. The model involves the primary and secondary deformation zones. The primary shear zone is modeled by a Johnson-Cook constitutive relationship and a shear plane having constant ...
